>> The `libNativeThread` was introduced to test the fix for [JDK-8237858](https://bugs.openjdk.org/browse/JDK-8237858). However, `JDK-8237858` only exists in Java 10 and above. There is no `JDK-8237858` problem on Java 8, so `JDK-8237858` cannot be backported to Java 8.
>> In order to use `libNativeThread`, I copied it to my backport.

@phohensee I didn't see your approval. Is it because this pull request has been closed by bot. I've reopened it, would you try again ?
